Movie Maker Problem Please Help

I have spent the past 3-4 hours editing a highlight/montage/action reel not quite sure the definite definition but i had quite a lot of content on that project and so i would save every 3 bits of editing as using movie maker with that much content it tends to glitch out and throw tantrums. As i split a video i noticed one of the glitches occurring and i haven't recently saved so i quickly saved before the software became unresponsive. I thinking "phew what a close call" i closed down Movie Maker and open up my project again..... to find nothing there...... the wmlp file has data on it about 99.8kb but when i select that file to open on Movie Maker nothing loads. Movie Maker says there is items there "1 of 143" what it usually says. I try hitting play and the timer is going but it's just black. 

Please please is there anything i can do. I really need that movie and i don't have the time to edit the movie again. It's not my computer specs as my hardware is gaming grade. Thanks so much for reading and i look forward to your replies.
